Not technically true anymore, as the new Kaby Lake Pentiums now have 2c/2t.![]()
The Pentium's are not i3's, they are i3's in the same way AMD's Athlon 860K is an FX-4300.... they ain't, for a start both have no L3, they are also missing several instruction sets.
The Pentium's are cheaper than the i3's because they are not i3's.
Edit... the G4400 is also 2C 2T.... https://ark.intel.com/products/88179/Intel-Pentium-Processor-G4400-3M-Cache-3_30-GHz
